In case of gears the pressure angle is

A.	The angle between the line of action and the common tangent to the pitch surface in the plane of rotation	B.	The angle between the normal to the point of contact and the shaft axis
C.	The angle between the normal to dedendum at the path point and tangent to the dedendum at the path point and tangent to the dedendum at the same point	D.	The angle of obliquity between the tangent drawn at the point of contact of the two mating gears
E.	None of the above

112.

The angle of obliquity is kept small in order

A.	To reduce force of friction	B.	To minimise axial load
C.	To minimise power loss in gearing	D.	To avoid larger throusts
E.	None of the above

113.

The standard pressure angle is generally

114.

Higher pressure angle results in

A.	Weaker teeth	B.	Non-uniform motion transmission
C.	Bigger size of gear teeth	D.	Wider base and stronger teeth
E.	Narrow base and weaker teeth

115.

In case of spur gears the top land is

A.	The part of the tooth surface lying below the pitch surface	B.	The curve forming face and flank
C.	The width of the gear tooth measured axially along the pitch surface	D.	The surface of the top of the tooth
E.	Radius that connects the root circle to the profile of the tooth

116.

The curve traced by the end of a thread as it is unwound from a stationary cylinder is known as

117.

Which of following gear system have minimum axial thrust?

118.

Stub tooth is

A.	Standard gear tooth	B.	Equivalent rack tooth
C.	Longer than standard tooth depth	D.	Shorter than standard tooth depth
E.	Non-standard tooth

119.

In case of involute gears

A.	Interference is inherently absent	B.	A convex flank is always in contact with concave flank
C.	Variation in centre distance of shafts increases radial force	D.	Pressure angle is constant throughout the teeth engagement
E.	None of the above

120.

A standard gear cutter No. 3 is marked to cut 35-54 teeth. It implies that

A.	The cutter is to be replaced after cutting 54 teeth	B.	The cutter will be suitable for gears having 35 to 54 teeth
C.	The cutter will be suitable for spur gear teeth cutting only	D.	The cutter will provide correct profile for any gear having number of teeth in the range 35 to 54
E.	None of the above
